Bizarre Plot Behavior
I have encountered a strange problem in MMA for Windows(Ver.2.2). I asked to plot a function which is a linearly bounded Cosine type function. When I plot on a certain interval, the first portion of the Cos wave(from (0,1) to (Pi/2,0)) is inverted and plotted from (0,-1) to (Pi/2,0). The rest of the waveform is correct. When I change the interval, the plot corrects itself. Is there something in the sampling scheme that would cause this? Has anyone else encountered this? Thanks in advance, Daryl P.S. If anyone wants to see this, I'll send you the whole notebook but it's fairly lengthy so I figured I'd save you all the reading.
